SHOCK-CORD KNOTTER.

Specification of Letters Patent.

Patented Feb. 11,1913.

Application filed June 1, 1912. Serial No. 701,032.

To all whom it may concern."

Be it known that we, WILLIAM J. KALI- NOUSKI and ALBERT PETERS, citizens of the United States, residing at Baldwin, in the county of St. Croix and State of Wisconsin, have invented certain new and useful Improvements in Shock-Cord Knotters, of which the following is a specification.

Our invention consists particularly in a hand actuatable device for tying together the ends of a binding cord, such as a binding cord carried around a shock of corn, said device including means for holding the cord under tension, cutting the same and knotting the 'cut ends.

To this end the invention consists in the features of construction, combination, and arrangement of parts hereinafter described and claimed.

In the accompanying drawings forming part of this specification, Figure 1 is a perspective view of our improved invention; Fig. 2 is a sectional detail of part of the same illustrating a spring pressed guide;

Fig. 3 is a detail view showmg the handle of the device and means for holding the cord under'tension; Fig. 1 is a detail view of a cutting knife forming part of the invention; Fig. 5 is a section on line 0am of Fig. 4; Fig. 6 is a side elevation of a cord knotter forming part of the device; Fig. 7 is a section on line y-y of Fig. 6; Fig. 8 is a. de tail view of a hinged jaw forming part of the knotter; Fig. 9 is a top view of the mechanism shown in Fig. 6; Fig. 10 is a side view, broken away, of the jaws of the cord knotter; and Fig.11 is a sectional detail of part of the means for holding the cord under tension.

. Referring to the drawings A represents an inclosing framework having an extended 'front wall 2 designed in use to be held 7 closely against the sides of the shock. Carried by the rear wall 3 is a pivotally supported handle a, the rear movement of the upper end of said handle being limited by formed with a groove 13 to receive the edge of the disk. The do is held in engaging contact with the disk Ty a spring 16. Having pivotal support 17 adjacent the inner side of the disk 9 is a cutter 18, having at its lower end a cutter blade 19. The cutter is normally held in dotted position shown in Fig. 4'by a spring 20 connecting the cutter with the supporting framework. The front wall of the framework is formed with an inlet opening 21, in one side of which is jour naled an anti-friction wheel 22. In the front face of the wall 2 at the opposite side of the-opening 21 is a pivotally supported guide 23 normally held pressed upwardly against a post 24 by a spring 25. The free end of the guide is inwardly curved to cooperate with the grooved edge of the wheel 22 to form a passageway for the cord, the upper side of the free edge of the guide nor mally standing close to the upper side of the anti-friction guide wheel.

Supported by a bracket 26 on one side wall of the frame A is our improved knottor shown specifically in Figs. 6 to 10. The knotter consists of an outwardly extending jaw member 27 carried by the lower end of a vertical post 28 journaled in the bracket. Secured upon the upper end of the post is a handle 29 normally held in the slot 30 in the bracket by means of the spring 31. The inner end of the handle may be rounded as shown to allow it to be lifted at its outer end out of locking engagement with the slot 30, the handle being suitably secured from turning upon the post as by having the post and the receiving opening of the handle squared. Having pivotal support 32 upon the fixed jaw 27 is a cotiperating jaw mem ber 33. The rear end of the aw member 33 carries a shoulder 3 1 to engage with a cam shoulder upon one side of the bracket to open the jaw. The continued turning of the post will carry the shoulder 34 away from the cam shoulder 35 into contact with a cam guide 36 closing the jaw.

In operation, the cord will be carried through one of the slots 10 of the disk 9 and the wheel then turned by the handle 4 to carry the cord underneath the dog 11, and hold the cord between it and the disk. The cord will then be carried over the knot- .ting jaws 33 and 27 through the opening said disk to in epen the shock to cause the tightest possible bindanti-friction roll. The cord is then passed around the shock, the end of the cord, after being passed around the shock, being passed through the opening 21, over the lmottmg jaws 27 and 33 and through one of the notches 10 in the disk 9, the free end of the cord then being pulled tight to cause it to tightly bind the shock, the disk then being. again turned to bring the free end of the cord between said dog and disk. With the operation thus far carried out the cord that has been carried around the shock will be held under tension by the disk 9, the front plate being preferably held tightly against ing of the shock. The post '28 when rotated to turn the jaws will, by reason of the cord passing over the top of the jaws, wind the cord around the jaws, and as the jaws reach the open position shown in Fig. 6 the part of the cord passing from the jaws to the disk 9 will pass between the open jaws. As the jaws are turned beyond the osition shown in Fig. 6'the cam guide 36 Wlll close the pivoted jaw upon the cord and the knife can then be lifted to out the cord. The device may then be pulled away, causing the cord to slip off the jaws. As the cord which is wound around the jaws slips therefrom it will pass over the cut ends of the cord which stands between the jaws, forming a knot noeaeea a cord extending through adjacent notches, an associated cord cutter and a knotting device comprising a fixed jaw rotatably supported inside said frame and a jaw vpivotally supported by said fixed jaw and cam* successively opening and closing said pivoted jaw as said jaws are opened, a cord holdingdevice comprisin" a disk formed with a plurality of pcrip eral notches rotatably supported upon the side of the frame op osite said cord guidewayland a dog perip erally engaging said disk whereby the cord may be initially passed through.

one of said slots and secured under said dog, and the op osite end of said cord after being passed 't rough said guideway and returned may be. secured in one of the sucin the free ends of the cord, and leaving the ceeding disk slots under said dog, and a cutshock tightly bound.

We claim as our invention:

1. A hand actu'at-able cord knotting device of the class described comprising a frame formed at one side with a guide wa a disk rotatably supported at the other si e of the frame and formed with a plurality. of peripheral notches, an actuating handle for sald disk, a do peri herally engaging with ently hold the ends of ting knife interposed between said cord holder and knotter.

In testimony whereof we afiix our signatures in presence of two witnesses.
